Abstract (en)
[origin: WO0108340A1] The invention relates to a method of providing error protection for a data bit flow in a digital telecommunication system, especially for speech signals that transmit speech in a mobile radio telephone system. The aim of the invention is to reduce the bit error rate of such a data bit flow. To this end, a plurality of known dummy bits are inserted at predetermined bit positions of the primary data bit flow in the proximity of significant information-carrying bits before channel coding is carried out.
